MIT chemists determine molecular structure of SARS-CoV-2 protein

MIT chemists have determined the molecular structure of a protein found in the SARS-CoV-2 virus. This protein, called the envelope protein E, forms a cation-selective channel and plays a key role in the virus's ability to replicate itself and stimulate the host cell's inflammation response.

Study sheds light on DNA sculpting properties of enigmatic protein

Sometimes, when something is broken, the first step to fixing it is to break it even more. In a recent example, scientists seeking to understand the mechanism of a DNA-repairing enzyme have discovered that the molecule performs its functions by first marking and then further breaking damaged DNA.
